Title (EN) CONFORMABLE STRUCTURED THERAPEUTIC DRESSING
(FR) PANSEMENT THÉRAPEUTIQUE STRUCTURÉ CONFORMABLE
Abstract:
(EN) A conformable structured therapeutic dressing (120) has maximum available surface area (102) of a therapeutic agent (122) to stimulate therapeutic response in wounded tissue of a mammalian subject. In preferred embodiments, the therapeutic agent includes a procoagulant to quickly arrest bleeding and prevent life-threatening blood loss. The wound dressing exhibits a structured adsorbent (104) that maximizes available surface area of a functional filler (72). This is achieved with a minimal amount of binder (82) and small, porous particles of the functional filler. Minimizing the binder maximizes the amount of functional filler and reduces the chance that the binder will block access to the surface area of the functional filler. Porous particles have a large internal surface area. Structured adsorbents with higher surface areas, higher inter- and intra-fiber porosities, and low internal mass transfer resistances produce higher rates of mass transfer of an adsorbent onto the functional filler.
(FR) L'invention porte sur un pansement thérapeutique structuré conformable (120) offrant un maximun de surface disponible (102) pour l'agent thérapeutique (122) pour stimuler une réponse thérapeutique dans un tissu lésé de mammifère. Dans les exécutions préférées l'agent thérapeutique comporte un procoagulant arrêtant rapidement le saignement et empêchant les hémorragies menaçant la vie. Le pansement comporte un adsorbant structuré (104) qui maximalise la surface utile disponible de véhicule fonctionnel (72). Cela s'obtient avec une quantité minimale de liant (82) et un véhicule fonctionnel de petites particules poreuses. La réduction du liant accroît l'augmentation du véhicule fonctionnel et réduit le risque de blocage par le liant de l'accès à la surface utile du véhicule fonctionnel. Les particules poreuses présentent une importante surface utile intérieure, et les adsorbants structurés en raison de leur surface utile accrue, de porosités inter et intrafibre plus élevée, et de leur faible résistance interne aux transferts de masse permettent d'accroître les transferts de masse de l'adsorbant vers le véhicule fonctionnel.
